Sorrento and Servier Enter Into Exclusive Worldwide License and Collaboration Agreement for Development and Commercialization of Anti-PD-1 Antibody
An Immuno-Oncology Therapy with Many Potential Applications

SAN DIEGO, July 11, 2016 /CNW/ -- Sorrento Therapeutics, Inc. (NASDAQ: SRNE, "Sorrento"), an antibody-centric, clinical-stage biopharmaceutical company developing new treatments for cancer and other unmet medical needs, and Servier, the largest non-listed pharmaceutical company in France, today announced a license and collaboration agreement for the development, manufacture and commercialization of products using Sorrento's fully human immuno-oncology anti-PD-1 monoclonal antibody (mAb) STI-A1110.

Sorrento's proprietary G-MAB library platform was used to identify and generate STI-A1110, which targets PD-1, one of the key targets in the rapidly developing immuno-oncology therapy market. The agreement provides Servier with an exclusive worldwide license to Sorrento's STI-A1110 mAb asset, covering all indications including hematological and solid tumor cancers. Servier also obtains full rights to develop, register and commercialize the products and will bear all costs for these activities.

The financial terms of the agreement include, among other things, a non-refundable upfront payment to Sorrento of €25 million. Sorrento may also receive development milestone payments for the initial product and each additional product. Sorrento may receive up to €710 million in various payments based on commercial sales milestones related to annual net sales levels for the initial product and then also for each additional product. In addition to the commercial sales milestones, Sorrento will be entitled to receive variable royalties on the sales of all commercialized products ranging from high single-digit to double-digit percentages.

"We are excited about partnering on our anti-PD-1 immune checkpoint antibody with Servier, which is recognized for its scientific excellency and as a pioneer in CAR-T therapies. This agreement represents validation for Sorrento's antibody technologies and R&D capabilities," stated Dr. Henry Ji, President and CEO of Sorrento. "This also further establishes Sorrento as a notable immuno-oncology company with a comprehensive portfolio of clinical stage and preclinical immunotherapies. We look forward to working closely with the Servier team and growing this global partnership."

"We have tested STI-A1110 in preclinical studies conducted at Servier and we believe that, used in combination with several products from our portfolio, it will lead to the development of new treatments for hematological as well as solid tumor cancers," added Dr. Jean-Pierre Abastado, Director of the Oncology Innovation Therapeutic Pole for Servier.
